Taking out the equation of line in the given questions

What is Slope-Intercept?

One of the most popular ways to represent a line's equation is in the slope intercept form of a straight line. When the slope of the straight line and the y-intercept are known, the slope intercept formula can be used to determine the equation of a line ( the y-coordinate of the point where the line intersects the y-axis)

9) slope = 2/3 and points (-1, 2)

Slope intercept form is y=mx + b. In this equation, m is the slope and b is the y-intercept. Point slope form is y-y1= m(x-x1). In this equation, m is again the slope and x1,y1 is where you plug in points from the line.

To solve this problem:

y=mx + b

2 = (2/3)(-1) + b

2 = (-2/3) + b

2 + 2/3 = b

(6 + 2)/3 = b

4/3 = b

so slope intercept form is y = (2/3)x + 4/3

10) slope = 5/4 and points (12,15)

Slope intercept form is y=mx + b. In this equation, m is the slope and b is the y-intercept. Point slope form is y-y1= m(x-x1). In this equation, m is again the slope and x1,y1 is where you plug in points from the line.

To solve this problem:

y=mx + b

15 = (5/4)(12) + b

15 = (5)(3) + b

15 = 15 + b

15 - 15 = b

b = 0

so slope intercept form is y = (5/4)x + 0

11) slope = 4 points (0, -1)

Slope intercept form is y=mx + b. In this equation, m is the slope and b is the y-intercept. Point slope form is y-y1= m(x-x1). In this equation, m is again the slope and x1,y1 is where you plug in points from the line.

To solve this problem:

y=mx + b

-1 = 4(0) + b

-1 = 0 + b

-1 = b

so slope intercept form is y = 4x - 1

12) slope = -1/4 and (1,-1)

Slope intercept form is y=mx + b. In this equation, m is the slope and b is the y-intercept. Point slope form is y-y1= m(x-x1). In this equation, m is again the slope and x1,y1 is where you plug in points from the line.

To solve this problem:

y=mx + b

-1 = (-1/4)(1) + b

-1 = -1/4 + b

1/4 - 1 = b

(1 - 4)/4 = b

-3/4 = b

so slope intercept form is y = (-1/4)x - 3/4

The given angles are- a= 62, b = 25, c = 99, d = 141, e = 42, f = 76, g = 88, h = 100, k = 72, m = 104, n = 71, p = 118, q = 82, r = 94, and s = 121.

Here, we are given a figure as shown in the image above.

We know that angles on a straight line are supplementary, that is, the sum of all the angles on a straight line is 180.

Thus, we can easily form the following equations and find the angles-

a + 118 = 180

a = 62

a + 93 + b = 180

⇒ 62 + 93 + b = 180

b = 25

3b + 6 + c = 180

75 + 6 + c = 180

⇒ c = 99

c - 60 + d = 180

99 - 60 + d = 180

⇒ d = 141

d- 3 + e = 180

141 - 3 + e  = 180

⇒ e = 42

2e + 20 + f = 180

84 + 20 + f = 180

⇒ f = 76

f + 16 + g = 180

76 + 16 + g = 180

⇒ g = 88

g - 8 + h = 180

88 - 8 + h = 180

⇒ h = 100

h + 8 + k = 180

100 + 8 + k = 180

⇒ k = 72

k + 4 + m = 180

72 + 4 + m = 180

⇒ m = 104

m + 5 + n = 180

104 + 5 + n = 180

⇒ n = 71

n - 9 + p = 180

71 - 9 + p = 180

⇒ p = 118

p - 20 + q = 180

118 - 20 + q = 180

⇒ q = 82

q + 4 + r = 180

82 + 4 + r = 180

⇒ r = 94

r - 35 + s = 180

94 - 35 + s = 180

⇒ s = 121

Thus, we get the given angles as- a= 62, b = 25, c = 99, d = 141, e = 42, f = 76, g = 88, h = 100, k = 72, m = 104, n = 71, p = 118, q = 82, r = 94, and s = 121.

If Fred and Bob share sweets in the ratio 3:7, Bob gets 48 sweets more than Fred. There are 120 sweets in total.

A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0.

By given

Fred and Bob share sweets in the ratio 3:7 ,Bob gets 48 sweets more than Fred.

Let x be the sweets with Fred.

Apply cross multiplication

3(x+48)=7x

Apply distributive property on left side.

3x+144=7x

Subtract 3x from both sides.

144=7x-3x

144=4x

The tip of the minute hand moves in a circle of radius exists 6 in. In 25 minutes, the tip of the minute hand moves 15.7 in

The arc length of a circle can be estimated with the radius and central angle utilizing the arc length formula, Length of an Arc = θ × r, where θ is in radian. Length of an Arc = θ × (π/180) × r, where θ exists in degree.

The tip of the minute hand moves in a circle of radius R = 6in.

We will find that for each case, 15 minutes and 25 minutes, the distance traveled is 9.42 in and 15.7 in correspondingly.

Remember that the length of an arc is defined by an angle θ in a circle of radius R is given by:

L = (θ/360°) × 2 × pi × R

We know that R = 6in.

To find how much the tip of the minute hand moves in 15 minutes.

Then we need to find the angle θ that the tip moves in these 15 minutes.

Remember that a complete rotation in the clock has 60 minutes.

This means that there exists an equivalence:

60 min = 360°

1 = (360°/60 min)

15 min = (15 min) × (360°/60 min) = 90°

Then, in 15 minutes, the tip of the minute hand moves:

L = (90°/360°) × 2 × 3.14 × 6in = 9.42 in

For the case of 25 minutes the procedure is the same:

25 min = (25 min) × (360°/60 min) = 150°

Then, in 25 minutes, the tip of the minute hand moves:

L = (150°/360°) × 2 × 3.14 × 6in = 15.7 in

Therefore, the correct answer is 15.7 in.

The probability least 1 zodiac sign match astrological signs is just the product of (12/12)(11/12 … (8/12).

Mathematical explanations of the likelihood that an event will occur or that a statement is true are referred to as probabilities. A number between 0 and 1 represents the likelihood of an event, with 0 generally denoting impossibility and 1 denoting certainty. How likely something is to occur is known as its probability. We can discuss the probabilities of various outcomes—how likely they are—when we aren't sure how a particular event will turn out. Statistics describes the examination of events subject to probability. Probability is a synonym for potential. It is a field of mathematics that examines how random events happen. From zero to one, the value is stated.

Let's solve for the following:

• (a). Find the value of the investment if the interest is 6.2% compounded monthly.

Apply the compound interest formula:

Where:

• P is the principal = $3000

• r is the interest rate = 6.2% = 0.062

• n is the number of times compounded = monthly = 12 months a year

• t is the time in years = 10 years

Plug in these values and solve for the value, A:

Therefore, if it is compounded monthly, the value at the end of 10 years is $5567.89

• (b). 6.2% compounded daily

In this case, the number of times compounded will be:

n = 365 times a year.

1. y = 100 × [tex](1 - 12)^x[/tex] = 100 × [tex](-11)^x[/tex]

Because (-11) is a negative number, y is not an exponential function.
